Hi Helmut!

❝ Well, if the study was planned for 80% power, CV <50%, and a GMR of 1 you would need 21. With a lot of drop-outs… In a full replicate (CV 30, GMR 1) you need only 16.

16 to finish I assume?

❝ ❝ It's risky enough to run a regular submission BE study with n=12 already... Is it? With EMA I never had any problems.

I've been dealing with too many nasty drugs...

❝ ❝ I will go check with my professor and see (Dr.Endrenyi) when I go have dinner with him later...

❝

❝ Best regards! Tell him that we haven’t forgotten the α-inflation story (hint). Detlew just returned form his vacation.

Will do

John
